Don't know. If you are going for a 23" + monitor, try to get a 4k display. 1080p even at 23" is just okay.
I'm not in SL and have no idea about the stuff anymore. :no:
Try eglobe solutions, redline or nanotek.
EPSI might have ASUS ones too.
I've used 2 x 23". It's kinda normal and should be okay after getting used to it.
I would suggest 1 x 27" or 2 x 23".
I have no idea about 32" monitors.
This one has a resolution of 1080p. I would say it's too low for a monitor of that size.
